Speaking in terms of putting into practise what we can learn from MN 75. Even in a state which is pleasurable, there is a clinging, a worry that this state might dissappear (which in fact it does) and will then be replaced by a state which is not the same, unpleasant, when compared to the state of pleasure.
We can see this in just about any kama tanha (desire for sense pleasure), even mundane things like conversation. If someone tells a particularly good joke, it's often followed by a period of uncomfortable silence. You have your momentary pleasure, but is it justified by the period of uncomfortable stress that follows?
I'm sure there are a lot of people here who understand this a lot better than I, because I'm just a beginner really, but it's interesting isn't it. Wonderful is the Dhamma, when we see the sublime truth is every thing we do.
P.S I hope I'm not spamming
"For a disciple who has conviction in the Teacher's message & lives to penetrate it, what accords with the Dhamma is this:
'The Blessed One is the Teacher, I am a disciple. He is the one who knows, not I." -
